INSTALLATION

41 INITIAL LIGHTING

1.Check that the system has been filled and that the boiler is not air locked.

Note.

It is important the burner is not operated before the system is fully vented of air. If it is necessary to operate the appliance pump to assist venting of the air this must be done with the gas service cock turned off.

2. Check that all drain cocks are closed and any valves in the flow and return are open.

3. Check the electrical supply is off.

4.Ensure the boiler sealing panel is fitted.

5. Check the gas service cock is open.

6. Check that the boiler on/off switch (A) is OFF

7. Slacken the screw in the inlet pressure test point (G) and connect a gas pressure gauge via a flexible tube.

8.Switch the electricity supply ON and check all external controls are calling for heat.

9.Set the boiler thermostat knob (B) to position 6 and switch the

boiler on/off switch (A) to ON. The boiler control should now go through its ignition sequence until the burner is established.

10. If the boiler does not light after 3 attempts the fault codes L' 'F' will be displayed. Press the reset button (E); the boiler will then repeat its ignition sequence. When the burner is established the WHITE burner ON neon (D) will be permanently illuminated

11. Ensure that with the boiler operating the dynamic gas

pressure is able to obtain maximum output. Refer to Table 2.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

INSTALLATION

N.B. The principle of the 1:1 gas valve ensures that the icos HE range is able to deliver it’s full output at inlet pressures down to 14mb. However if dynamic pressures below 20mb are experienced ensure this is adequate for ALL other gas appliances in the property.

IMPORTANT.

The gas input to the burner is regulated by the gas valve according to the air flow produced by the fan. It is NOT user-adjustable. Any interference to sealed settings on the gas valve will adversely affect operation and render our warranty void.

12.Switch OFF the boiler on/off switch.

13.Remove the pressure gauge and tube. Tighten the sealing screw in pressure test point. Ensure a gas tight seal is made.

14.Refit the boiler front panel and bottom panel.

15.THE FASCIA

a.To remove the plastic fascia, prise off the retaining star washers using a pair of pliers and place to one side.

b.Fill the remaining fixing holes with the white push in caps provided.

THE DISPLAY

The user control has one neon and one display to inform the user about the status: the display will show the status of the boiler and the neon will show the status of the flame. If no flame is detected the neon is blinking. When the flame is detected the neon will be lit permanently.

Below is a list with display function in normal operation.

Standby. No demand for heat present.

Boiler is active for central heating.

Boiler is in lockout for a specific error. The display will be blinking, alternating with a number or letter to show which error is detected.

Boiler is in lockout for a specific error. The display will be blinking, alternating with a number or letter to show which error is detected.

Boiler frost protection

Note: Boiler frost protection occurs at a temperature less than 3 degrees. The boiler will fire.
